Hello,

i am trying to use a com component in an ASP.NET
application. But it gives me an error as follwos:
"System.Runtime.InteropServices.COMException: Object
variable or With block variable not set"
i used the COM file thru ASP and that worked very well.
but the same file i cannot access thru ASP.NET
i do not understand why?
Can anyone PLEASE HELP ME?

Try setting the ASPCOMPAT="True" attribute at the top of your ASP.NET page,
to ensure that your COM+ component is called from an STA thread, and not an
MTA thread.

For more information on STA/MTA and the ASP.NET threading model, see
http://msdn.microsoft.com/.
